Abstract: A method for providing, e.g. by means of an application (S_APPa) installed on an Universal Integrated Circuit Card (108a),a response to a SCP80 command is described. Initially, a first SMS message is received, e.g. by means of a mobile device (10), from a remote server (MNO) and decrypted according to the protocol SCP80. Specifically, this first SMS message contains a first command requesting the execution of a proactive command. Once, the proactive command has been executed and a respective response has been obtained,a second SMS message (SMS3) is transmitted to the remote server (MNO) indicating that the response has been obtained. Next, a third SMS message (SMS4) is received from the remote server (MNO)and decrypted according to the protocol SCP80. Specifically, this third SMS message (SMS4) contains a second command (C-APDU2) requesting the transmission of a response message determined as a function of the proactive command response(RSP1). Accordingly, the response message (R-APDU1)may be generated, encrypted according to the protocol SCP80 and transmitted(SMS5) the remote server (MNO).

Abstract: A communication interface (921) for interfacing a transmission circuit (901) with an interconnection network (701), wherein the transmission circuit (901) requests via a transmission request transmission of a predetermined amount of data. In particular, the communication interface (921) receives data segments from the transmission circuit (901), stores the data segments in a memory (922), and verifies whether the memory (922) contains the predetermined amount of data. In the case where the memory (922) contains the predetermined amount of data, the communication interface (921) starts transmission (924) of the data stored in the memory (922). Instead, in the case where the memory (922) contains an amount of data that is less than the predetermined amount of data, the communication interface (921) determines a parameter that identifies the time that has elapsed since the transmission request or the first datum received from the aforesaid transmission circuit, and verifies whether the time elapsed exceeds a time threshold. In the case where the time elapsed exceeds the time threshold, the communication interface (921) starts transmission (924) of the data stored in the memory.
